A G Minor (Gm) chord contains the notes G, D, A#. It is built from the minor formula 1 - ♭3 - 5, with G as the root.
Is there an easier way to play G minor?
Not really — G minor has no open-position shape, which is exactly why it's a rite of passage. The honest fix is to work on the barre itself: keep the index finger slightly rolled onto its bony side, and press just behind the fret rather than squeezing harder.
